Over the past several years, colloidal core/shell type quantum dots lighting-emitting diodes (QDLEDs) have been extensively studied and developed for the future of optoelectronic applications. In the work, we fabricate an inverted CdSe/ZnS quantum dot (QD) based light-emitting diodes (QDLED). In order to reduce work function of indium tin oxide (ITO) electrode for inverted structure, a very thin (<10 nm) polyethylenimine ethoxylated (PEIE) is used as surface modifier[1] instead of conventional metal oxide electron injection layer. The PEIE layer substantially reduces the work function of ITO electrodes which is estimated to be 3.08 eV by ultraviolet photoemission spectroscopy (UPS). From transmission electron microscopy (TEM) study, CdSe/ZnS QDs are uniformly distributed and formed by a monolayer on PEIE layer. In this inverted QDLEDs, blend of poly (9,9-di-n-octyl-fluorene-alt-benzothiadiazolo) and poly(N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] are used as hole transporting layer (HTL) to improve hole transporting property. At the operating voltage of 8 V, the QDLED device emitted spectrally orange color lights with high luminance up to 2450 cd/m2, and showed current efficacy of 0.6 cd/A, respectively.

This study was conducted to develop a Web-GIS based monitoring module of smart city that can effectively respond, manage and improve situation in all stages of illegal dumping management on a city scale. First, five technologies were set for the core technical elements of the module configuration. Five core technical elements are as follows; video screening technology based on motion vector analysis, human behavior detection based on intelligent video analytics technology, mobile app for receiving civil complaints about illegal dumping, illegal dumping risk model and street cleanliness map, Web-GIS based situation monitoring technology. The development contents and results for each set of core technical elements were evaluated. Finally, a Web-GIS based 'illegal dumping monitoring module' was proposed. It is possible to collect and analyze city data at the local government level through operating the proposed module. Based on this, it is able to effectively detect illegal dumpers at relatively low cost and identify the tendency of illegal dumping by systematically managing habitual occurrence areas. In the future, it is expected to be developed in the form of an add-on module of the smart city integration platform operated by local governments to ensure interoperability and scalability.

This paper aimed to examine core factors of the knowledge management and analyze their effects on organizational performance (employee satisfaction and competitive advantage). To accomplish this purpose, this study examined previous studies and summarized core factors of the knowledge management as people oriented, culture oriented and system oriented. 350 questionaries were distributed to the people living in Gumi. 327 questionaries were obtained and 302 data were analyzed by frequencies, correlation and multiple regression. The results of this study are as follows; First, we conducted exploratory factor analysis about three constructs (people oriented, culture oriented and system oriented) using oblique rotation method that did not assume independence among the factors and core factors of knowledge management were grouped together by three factors. Second, it is shown that three core factors of knowledge management have a positive influence on the employee satisfaction and competition (p<0.05). This study, however, have limitations in obtained sample and area. The future study should consider these limitations to improve model applicability in practice.

The generalization of social distancing due to the COVID-19 pandemic has rapidly spread non-face-to-face services, accelerating the speed of non-face-to-face digital conversion technology. The importance of telemedicine, a remote service, has been rekindled in the wearable technology including the medical industry. In a situation where it is not easy for any company to overcome the COVID-19 pandemic, it is a time when collaboration within the industry or between competitors is necessary. In addition to the digital-based online exhibition hall using AR-VR-MR technology, which is a major core technology of the future industry, virtual stores that can receive services such as actual shopping should be actively used. Paradoxically COVID-19 will provide new opportunities to reshape and reconnect the future of the textile and fashion industry. Therefore, the purpose of this study is to investigate the current status of wearable technology products being developed as fashion items for the prevention of COVID-19 and analyze their characteristics. This study results can be used as basic data for future research on the fashion industry and education.

국제적으로 국방예산은 감축하는 추세이나, 국방 R&D 투자는 지속적으로 확대하고 있다. 이는 주요국이 첨단기술 확보와 신개념 무기체계 개발을 통해 미래전에 대비하고 있음을 보여준다. 특히 4차 산업혁명 기술 발전은 미래전 양상을 가속화 시킬 것으로 예상되므로 우리도 첨단 무기의 독자 개발능력 개발과 미래전 대비를 위한 중·장기적인 국방과학기술 투자전략이 필요하다. 주요국 국방과학기술 정책, 전략수립 절차 등의 사례조사를 통해 국방과학기술 전략에 따른 투자전략을 수립 방안을 연구하였다. 우리도 주기적으로 국방과학기술 연구개발 목표와 방향을 수립하고 연구개발 전략을 제시하고 있으나, 5년 주기로 수립되는 국방과학기술 전략에 의존한 연구개발 추진으로는 급변하는 안보환경과 과학기술 패러다임 변화에 대처하는 데는 한계가 있다. 본 연구에서는 정부의 정책 추진 중점, 안보 위협 변화에 따라 수립된 전략의 수정·보완 시 이를 능동적으로 국방과학기술 연구개발 전략에 반영하기 위한 투자 효율화 프로세스를 제안한다. 전략 및 중점분야가 핵심기술개발로 연계되는 연속성을 유지하면서 기술변화, 안보환경, 국방정책의 니즈를 신속히 반영할 수 있는 프로세스는 국방연구개발 예산의 효율적 배분과 전략적 투자방향 설정에 활용될 수 있다.
